Patented Dec. 3, 1918 INVEN Bery'cmzz'n f Cba/Yf'ere Z BY f3 WITNESS W MW T A TTORNEY-IS' ens A PLASTER-BOABD CLIP.

To allwhomz't may concern Be it known that I, BENJAMIN F. Coon- ERELL, acitizen of the United States, residing-at Kansas City, Missouri, haveinvented certain new and useful Improvements in Plaster-Board Clips, ofwhich ,the following is a specification. f 1

The subject-matter of this invention is a metal clip for securingplaster-boards and the like .to metal studding-in the erection ofpartitions and other walls in buildings.

The clip ofmy present invention belongs to the one-piece type which arecut and pressed to shape from a single sheet-metal blank and areconnected to the studding without the use of fastening wires or anyother extraneous attaching means; and the and without embracing thecomplete stud,

- against rockingor tipping sidewise thereonprincipal objects of theinvention are:

First, to provide a metal clip whichmay be attached to a flanged studthrough engagement with the flange only of the latter,

edge of an upper plaster-board;

Third, to provide a'metal clip which can be applied with equal facilityand utility to either or both sides of the studding;

Fourth, to provide a metal clip which, when engaged with a stud,-shallbe held and shall be securely-locked to the stud when the plaster-boardis in place.

Fifth, to provide a metal clip of such a construction that by a slightadjustment of 1 the dies or other forming tools it can be made toholdplaster-board of any thickness or to engage with any size of studding;

Sixth, to provide an improved metal clip,

no portion of which has to be bent or changed inform or position whenapplying it to the studding.

Other, objects and advantages secured by the invention will be readilyapparent to, and appreciated by, those skilled in the art Specificationof Letters Patent.

from the following detail description, taken Patented Dec. 3, 1918.

' Application filed September 4,1917. Serial No; 189,499. I a i inconnection with the accompanying drawing forming a of this specificationand wherein- Figure 1 is a horizontal sectibn through a fragment of apartition wall employing my improved plaster-board clip, taken on theline 1-1 of Fig. 2;

Fig. 2 is a vertical section taken on th line 22 of Fig. 1; a

Fig. 3 is a detail perspective view of the clip; 1

In the drawing 5 designates an element of the metal studding of the inthis case a vertical channel-bar. These channels are commonly erectedfrom one to three feet apart along the line of thepartition and togetherfrom a skeleton support for a wall covering or filling that is appliedto either or bothsides of the studding and commonly consists ofrectangular plasterboards 6 that are assembled edge to edge.

[For attaching the plaster-boards -to the studding as well as properlyalining the meeting edges of the boards themselves,

partition wall,'

many different devices have heretofore been proposed and used. Toexpedite the work of erection and secure economies in material,

time and labor, it is manifestly desirable to make these plaster-boardfastening devices as simple as possible consistently withefliciency andparticularly to so construct them that they may be applied and locked tothe studding without 'the use of extraneous fastening devices or bendingor otherwise altering the shape or position of any part thereof. Theimproved fastening clip forming the subject-matter of my presentinvention possesses these and other advantageous characteristics, and isshown in plan view in Fig. 1, in cross-section in Fig.2, and inisometric detail in Fig. 3, from which it will 'be seen that the clip isformed from a single blank of sheet metal so cut and pressed to shape asto provide upper and lower channels for receiving the lower andupperedges respectively of two superposed plasterboards, and on one sidethereof means for securing it to the adjacent flange of the channel-barstud 5. Describing the clip more specifically, 7 designates a horizontalcentral web from one side of which extend marginal flanges 8 and 9 thatform, with the web 7, one of the plaster-board receiving channels, andfrom the other side of which extend in the opposite direction marginalflanges l0 and 11 that form, with the web 7, the other plaster-boardreceiving channel. The inner end portion of one of the flanges 8 iscutaway from the web and bent outwardly in the form of a hook 12 thatengages over the free edge and inner face of the adjacent flange of thechannel-bar 5 in the manner clearly shown in Fig. 1. Opposite the freeend of the hook 12 is a lug 13 that lies in the plane of the flangemembers 8 and cooperates with the hook to prevent sidewise turning orrocking of the clip on the stud 5. Between the non-turning lug 13 andthe other flange member 8 is a laterally projecting locking prong 14that cooperates with the hook 12 in holding the clip in proper relationto the stud.

The clip is applied to the channel stud 5 by first engaging the hook 12over the free edge of the flange of the stud while holding the clip in acanted or inclined position relatively to the plane of the studding, andthen, by a combined swinging and endwise movement of the clip, bringingthe automatic locking prong 14 into position directly behind the rearface of the stud 5, which at the same time brings the main body of theclip into correct plaster-board receiving position. hen in this positionit. will be manifest that the hook 12 prevents the clip from movingoutwardly away from the stud,

the hook 12 and prong let prevent endwise shifting of the clip in eitherdirection and also any substantial endwise tilting or rocking. and thehook 12 and h1g1?) prevent sldewise rocking or tilting, so that the clipis free for only a sliding up and down movement on the stud. It willfurther be noted that theclip may be applied with equal facility toeither side of the stud. the clip on one s1de being merely invertedrelatively to its position on the other side, as clearly shown in Fig.2.

In applying the plaster-boards to the studdlng, a row of clips on whichthe lower or depending flanges may be omitted if desired lsflrst appliedto the studs at the floor level. boards is then laid with their loweredges engaged with the clips. A second row of clips is then applied withtheir lower channels engaged with the upper edges of the plaster-boards.A second row .of plasterboards 1s then laid with their'lower edgesseated 1n the upper channels of the second row of'chps, and so on, untilthe partition wall is completed.

I claim:

boards and the like to flanged 'studding, comprising a body memberformed with a channel to seat the edge of a plaster-board, a hookprojecting laterally from a side wall of said channel and engaging overthe free edge of the adjacent flange of the studding, and a lockingprong projecting laterally from said channel on the same side of thelatter as said hook and engaging the studding at a point opposite thefree end of said hook.
